BOLT-HINGE.

SPECIFICATION forming part of Letters Patent No. 302,905, dated August 5, 1884.

Application filed December 19, 1883. (No model.)

.1 0 all whom it may concern Be it known that I, RICHARD H. GARLAND, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illin-ois, have invented a new and useful Bolt- E Iinge, of which the following is a specifica- Myimprovement relates to a peculiarly-constructed hinge, wherein I combine a screwthreaded bolt with wood, iron, or other material fashioned as hereinafter described.

Figure l is a vertical section of my invention, centrally broken away to show how the bolt is arranged; Fig. 2, a top view or plan of same; Fig. 3, a vertical view of bolt used; Fig. 4, a plan of Fig. 3.

Similar letters refer to si milar parts throughout the entire views.

a represents a section of wood or other material, rounded at one end, so as to form a knob, 12. A

0 represents a section of the same material as a, with a socket, d, cut in one side thereof, which occupies a portion of the arc of a circle. The socket d may be placed at any part of the material c-end, corner, upper or lower sideit depending on the use to which the hinge is put. In the present illustration it is shown as occupying an upper corner. When the parts a and 0 are brought together, theknob b will rest snugly in the socket d.

6 represents an eyebolt screw-threaded at one end to receive a hexagon nut, f, and fiattened at the other end to formatongue, g,with an eye, The tongue 9 is constructed with a shoulder, which rests, when in position, against a washer, 72..

Previous to uniting the parts a and c Idrill a hole, 2', centrally in the socket d, and then introduce the screw end of the bolt 6 therein through the washers h and j, which are embedded in the hole. The bolt e catches into the nut f below the washer j, and is turned down with an ordinary wrench untilthe shoulder rests against the washer h and the nut f against the washer j. The flat part of the tongue will stand parallel with the width of the part c. The knob b has a-slot, 0, cut longitudinally, half or little more than half the distance from outside surface toward the center of said part, which slot corresponds in width with the tongue 9, or it may be a trifle wider, and fits over the said tongue when the parts a and c are brought together. Apintle, 7c, is then introduced through the knob 12 into the eye 9 of the bolt 0, passing through said knob to the other side, and is there secured by riveting. The hinge is then perfected. In some articles where I employ wood to form my hinge, and there is much play on the pintle, causing it to wear in the wood, I then introduce a hollow tubing, 75', which embraces said pintle on either side of the tongue 9, and swage the pintle at either end, to prevent its with drawal WVhat I claim as new, and desire to secure by Letters Patent, is

The combination, in a hinge, of the parts a and 0, arranged as described,with an eyebolt, e, secured to said parts, as set forth, all constructed as and for the purpose specified.
